Perhaps you should try some spelling variations:
mengenal bangun » mengenal angka
lembaga negara » lembaran negara
dan mengenal » dekat mengenal, mudah mengenal, mari mengenal
ayo belajar » mari belajar
nuansa di » nusa di, nuansa 3
puasa di » puasa dan, biasa di, jasa di
negara 1 » negara di, negara ri
bangun 2 » bangunan 2, bangun ht

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( materi ((nuansa di) OR (puasa di)) lembaga negara 1 ) OR ( ayo belajar dan mengenal bangun 2 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( materi ((nuansa di) OR (puasa di)) lembaga negara 1 ) or ( ayo belajar dan mengenal bangun 2 ))~".
• Adding a wildcard symbol may retrieve word variants: (( materi ((nuansa di) OR (puasa di)) lembaga negara 1 ) or ( ayo belajar dan mengenal bangun 2 ))*.
